GENERAL WELDING SPECIFICATIONS FOR CONSUMABLE ELECTRODE WELDING METHOD

SCOPE: This specification applies primarily to welded aluminum connectors for substation construction. MATERIAL: CASTINGS—As furnished by Anderson are molded from 356 aluminum alloy and heat treated to T6 condition, or #99 pure aluminum depending on the application. FILLER ROD—043 aluminum alloy 1/16” diameter for all joints as shown in the Anderson catalog.

polarity is capable of handling the majority of aluminum welding jobs. PROCEDURES: It is of the utmost importance to remove oil, grease, water and oxide from the surfaces to be welded. All surfaces to be welded should be wire brushed with a stainless steel brush prior to welding. If more than one weld pass is required, the original weld should be wire brushed before applying additional weld. Pre-heating of surfaces to 400° E is optional, but by preheating the surfaces before welding it is possible for the operator to weld easily and faster.

SHIELDING GAS—Argon.

WELDING APPARATUS—Tungsten-arc (TIG) or metallic-arc inert gas shielding (MIG). A 400 amp welding machine with reverse
